Install AppSync Unified on iOS 9 for iPhone/iPad

The majority of the jailbroken iPhone/iPad users have AppSync Unified Cydia tweak installed on their device.

If you need to install iOS apps by downloading IPA files, you need to have AppSync Unified on your device. If you are willing to install apps on your device that are not on official App Store, you need to have AppSync.

The official apps have the signature of the developers of Apple App Store. Whereas, for 3rd party apps and IPA files, there’ll be no official signature. So, your iOS device refuses to install the app. Although in previous versions of iOS, you could trust the unknown developer under setting > profiles, in recent versions of iOS 9 downloading 3rd party apps without Cydia and AppSync installed is impossible.

In this post, I will explain you how to download and install AppSync Unified tweak on your jailbroken device, and before that how to add supported repo for your Cydia app.
